Video Editing in WP8 - Windows Phone 8 Apps and Games

Is there an OS level restriction preventing someone from making a simple video editor for Windows Phone? I'd love to see something with basic features like:
Trimming clips
making slideshows out of still pics
adding title frame to beginning and end
putting clips together
adding voiceover or music
text over video
I think those things could be done with the dual core processors, right? It seems like the most taxing would be adding audio since the phone would be playing video and recording audio at the same time.
Anyway, I was curious why no one has tackled this. I think it could even be a good commercial, money-making app.

ditto. would really like to see this as well.

[Q] recording audio with my streak

when i try and record audio (mp3s) with my streak the result comes out high pitched. the stock sound recorder quality isnt very good. I have been trying out mp3/wav recorders form the market.
it almost seems to be a sampling issue.....but the recorders bit rates are all set right.....cd quality, etc....
any ideas?..... is there something i need to change....?
also.....i installed cleartune......and to make it work right i had to make it transpose to D and set A=427Hz.....i installed another tuner called "datuner"....it works fine....
very frustrating cause im a band director and really need to record things on the fly.....but not high pitched.....?
Rehearsal Assitant - can't comment on using for high quality recordings, but works for voice for me.
cool....ty ...
tried it.....rehearsal assistant still uses a lower bitrate when recording. .wav recording doest work at all....it looks like it is recording but is not......and the files will close and crash the player...
i need a solution to record at high bitrates.
man.... i have tried i think every recording program on the market..... the only one that would record at 44.1k was "Livo Recorder"..... it will record .wavs that sound ok...but at 5-10 Mb/min.... .wavs are just way too big to use and email....
all the .mp3/other recorders would record but the files came out sounding like they were being played in a slow fast forward...
this is very frustrating..... is it the streak?....is it android 2.2?
i need this to work.... i need to record stuff all the time....and .3gp at 8k is not going to work for concert band recordings....the end result is too muddy sounding.....i dont record to keep...only for review... it is an essential aid when working my band
any ideas?.....and thank you for your help
Recordings are horrible!?!? Would love to find an anwser too
I have had the same issue and I would love to know what can be done. I have tried contacting the developers of various recording apps, but get no response from any???
im sure a lot of other streak cats and maybe some android users in general are having the same problem...
this is a real bummer for me actually.....this could be a serious deal buster for me...i may have to go back to my iphone i bought the streak as an upgrade to my jailbroken iphone 3gs.... iphone sucks but at least it does what it is supposed to do...and yes to make an iphone bearable you really should jailbreak it.....
i also had to root my streak to fix several other issues as well.....lol.... i had to "jail break" my streak....lol...
like the tuner issue im having....being a band director i NEED a tuner...it is a must have....i know i could just use a dedicated pocket tuner, but..... the point is that something is totally not working right in the streak or android....being able to record these days at CD quality should be a no-brainer to developers and/or hardware developers..... i was recording cd quality back in 2001 on my sx-66(the original XDA phone...) pocket pc phone....lol....
anyway,......any ideas?
anyone else having these issues?..... have you found something that works?
Maybe list the recorders you've already tried, so someone doesn't repeat. I've been using pcm recorder for voice recognition (naturallyspeaking), but of course that's only wav. Probably the difficulty lies in the licensing required for creating mp3's.
Would ogg recording do?

[Q] Video Playback Problems

For some reason when I try to play videos on my Galaxy Tab 10.1 they keep coming out choppy and pixilated. I tried the default player, Mobo, and RockPlayer, and the videos still come out all pixilated and choppy. I tried putting a few movies on there last night like Inception, The Dark Knight, and Limitless and they were all choppy and pixilated. I used .avi, .mp4, and .m4v formats, none of which worked. I even tried downloading vids encoded specifically to work on mobile devices such as iPod/PSP and they didn't work. I even downloaded HandBrake for Mac and followed the directions on Cnet and nothing played properly. Everything played choppy and pixilated on all the players.
A Google search showed that MANY people are all having the same problem, so I don't think it is an isolated issue with my specific Tab. How the hell can I play videos clearly on my Tab???
I use vplayer
try Diceplayer.... IT plays anything i throw at IT..... except 1080 mkv, they stutter sometimes
Use the low profile settings for handbrake from this thread: http://forum.xda-developers.com/showthread.php?t=1060825
Or use the Samsung Kies software and let it automatically convert the video for you when you transfer it to your device (handbrake is faster and slightly better quality imo).
Or as has been suggested already, try DicePlayer from the market and see if it works with your files.
MeGUI is the only way for top video quality in your tablet.
http://forum.xda-developers.com/showthread.php?t=1245668
mine doesn't even play divx.. on my galaxy s its no problem, it plays almost anything
Upload the sample-megui.mp4 file to your tablet and open it with Google Videos app. Let me know if it works and how is the quality. Make sure you tap on the 5.1CH logo to enable the 6 channels sound.
Not sure if you have an unlocked bootloader, but I heard that the Videos will force a bootloader lock. Mines is already locked, so I don't care...
I've the same problem. I've tried everything (change player, video quality, etc.) but the video playback still sucks. I hope the release of vlc for android will fix this issue, but I'm a little bit disappointed..

It may be an option but it isn't the ONLY option (Handbrake is at least one other proven option that many people here use), keep your marketing spam out of this thread.
Anyone who claims that their solution is the ONLY solution is clearly here to do some marketing.
In fact, for those who use MacOS or Linux, MeGUI is NOT an option, period.
Nah, no marketing here. Been on forums for a long time (Google my full name) and I hear what you say... sorry for misunderstanding. I'm an old member on doom9, they are hardcore video people. Handbrake is great for mobile devices, while MeGUI allows you to to encode your video's at any level you want.
Cheers
Please use the Q&A Forum for questions Thanks
Moving to Q&A
Heh, I was on Doom9 when Doom9 the dude was still a regular, and Gej was still pounding on DivX 3.11. Old times, eh.
As for MeGUI, it's not the only front-end around. If you're on Doom9, then you know better. Most do basically the same thing, which is to run x264.dll plus some processing via AVISynth. Each front-end has its own strengths and weaknesses.
Despite its dinosaur interface, Handbrake is still more user friendly than MeGUI or most front-ends, and it does the job more than well enough. The auto-IVTC works well.
MeGUI allows more manual fiddling, as of course do most geek tools. It's been around a while, and there are newer "geek" front-ends with better UI. But for the hardcore, the "only way" is to ignore front-ends and use the tools directly, ie x264.exe and AVISynth, and write scripts as needed.
Check out my "conversion" script below. It's a geek tool geared for noobs (only one menu), but is infinitely adjustable for geeks. The script is only a text file, after all.

I totally agree with you, MeGUI is a pro tool not intended for the novice user. However, as you said it so well, you can't beat MeGUI's customization levels allowing you to achieve amazing results. I get both of worlds, I do my own AviSynth scripts directly into MeGUI... I encode all my Bluray's with it for Media Center and push the data through Yammm. Now that I got a tablet, is time to redo some of my faves for the P7510.
BTW, good fortune with Searchlight and Axivo.

[Q] Is it possible to record any video with CFR (Constant Frame Rate)?

Here's what I want to do: I'd like to be able to take multiple videos throughout the day and then at the end of the day join them together as one video to upload to YouTube.
Here's the problem: I can't join videos together that are VFR (variable framerate). They need to be converted to CFR first. However, no matter how I try converting them, I always end up with audio/video sync problems. I've spent days and done lots of research and tested several programs/methods to accomplish this. There's still more for me to try, but so far I've not been successful.
Which brings me back to: If I can just get the RAZR to record videos with a constant framerate, the above problem(s) should be eliminated.
My current favorite camcorder app is the LG Camera ("LG" having no relation to the electronics manufacturer). It has many options and blah blah blah. One of the options is to set the framerate. Offers selections as low as 2 FPS up to 60 FPS. Unfortunately (and I have emailed the dev about this), changing this setting doesn't seem to have any effect.
This could be because of a firmware limitation of the device itself, or it could simply be a bug with the app. I don't know yet. I'm trying to find out.
I did find another post around here about recording videos at 120 FPS or something like that. Seems that making some edits to the build.prop file made the phone think it was recording at that FPS but the resulting file showed otherwise. Well, I'm not looking for any real high FPS for my videos. I figure somewhere around 30 should be good enough. The only thing I really want to know is if there is any possible way I can force the camera to record at a constant framerate.
Perhaps the build.prop file can be edited to allow this. I'm not sure. I certainly hope this is possible one way or another, though.
Thanks for your time.
I was one of the people doing the 120fps experiments, and as you noted, nothing worked. I'm thinking the cpu is simply sending a stream of data that the phone must accept.
I'm pretty sure the phone records in a variant of motion jpeg, and simply takes up to 30 stills per second. I've edited these files myself, and it's a pain in the a**.
You need to find a setting in your video editing app that allows for variable framerate content. VFR for short.
Also, .avi containers doesn't support VFR content. You need to save to MKV, MP4, WMV or ASF. Probably more containers, but those are common.
Thanks for the response.
Well, bad news and good news.
Bad news is, I was never able to find any program that could properly convert and/or join the video files without blatant sync problems as a result.
The good news is that the above is not 100% true. After posting my question, I had received some help elsewhere and ended up using ffmpeg and MEncoder (both command line tools for video processing). ffmpeg converts the files to CFR and then MEncoder joins them together. These two utilities combined with the automation power of AutoHotkey allowed me to create an AHK script that will convert and join all the videos successfully simply by dropping the files in the folder and running the script.
In the rare case someone else comes here with the same problem, here's the video-help thread that brought me to this solution: ~~~ Okay, I can't post links. In that case, here's a sample command line for converting the file to CFR:
Code:
ffmpeg -i input01.mp4 -c:v mpeg4 -b:v 1800k -c:a copy -vsync 1 -r 25 temp_output01.mp4
You'll have to run ffmpeg separately on each file, I believe.
Here's a sample MEncoder command line for joining the converted files together:
Code:
mencoder input01.mp4 input02.mp4 input3.mp4 -vf harddup -ovc copy -oac mp3lame -lameopts cbr:br=128 -o joined_output.mp4
You can enter in as many input video filenames as you want to join together.
After I found a solution for converting and joining, I decided to leave this post up because I still wanted to find out if recording in CFR on the Droid was possible. I'm guessing it isn't. That's too bad.
I read about that actually, problem is that directly converting to CFR makes the video somewhat choppy. As you are either playing the same frame twice, or removing a frame to compensate for the fps you're using.
If I'm not too confused, you can interpolate the missing frames to make it appear smoother. At least in some video editors.
Yeah. Fortunately, so far I haven't noticed any obvious issues with the final video.

[Q] record video while running other app?

I just got my new galaxy note (i717) on friday (immediately flashing it with OnlyOne beta 2 (ics)) and I would like to use it for a bit of podcasting using the front camera to record myself while I read text from some teleprompter software.
I can record video from the front camera just fine, and it actually comes out a bit higher quality than I expected even, but for the life of me, when i hit the record button and then switch away from the camera app to the prompter app, it gives me an audio notification that the camera has stopped recording.
is there prompter software that has an integrated video recorder? (that'd be pretty sweet imho) or better, some way to record video while another app (that's not particularly resource intensive) is in use? - I don't mind trimming and cutting the video together (there are actually some pretty decent editing tools for android i've found) but I can't figure out a way to record and prompt at the same time...
does anybody have any ideas?
I'm rather surprised that nobody seems to have any ideas on this... could someone at least please relay to me why this isn't possible (if it's not possible)?
I would think that this would be a reasonably popular thing to do (recording video whilst looking at a prompter or even a web page or something to do podcasting stuff...
Is this something I'm going to have to write? (I have no idea how to dev android apps).
well i'm glad to see that google does a good job at finding appropriate threads - here it is, a couple of months later, and I'm revisiting the same problem that I had before - I still can't record and prompt at the same time on my i717 (now running cm9 / cm10, not that it should matter)... I still don't get it.
i don't know what to say , u searched a program on google?i believe that is here at least 1 program for your note
Video app with built in teleprompter
There is a great teleprompter/video recording app. It's called VRT2. Unfortunately you would have to downgrade to an iPad to get it. When I saw it, I was tempted o make the switch, but I don't want to give up the advanced features of my Samsung Note 10.
I'm hoping that a great Android app developer will create something like the VRT2 soon.
When it's ready, I'm ready to buy it.
I still can't seem to find anything that does this and it would be *great* for quick video podcasting... I just want to be able to record myself on the front camera while either reading my notes or looking at a teleprompter with the outline i've created for the segment.
Video recorder teleprompter
Have you found any other software to video you with front facing camera with teleprompter on screen?
I know Ipad have one on itunes costing somewhere 24 dollars or £18 which is a professional one, not tried it but I now it does record you and at the same time has all the words you want to talk about in front of you.
Keep up to date, I don't know which tablet to buy because of this problem.

[Q] HP TouchPad advice for my Grandmother

Hello everyone,
So like many of you I picked up an HP TouchPad when they were on sale. I gave the TouchPad to my Grandma. I figured it would be worth it alone for just using it as an interactive photo frame. With 32GB of space to spare I even put some QuickTime videos converted from home video VHS tapes.
While it works well for that, the organization of the Photo program on WebOS isn't the best. Viewing photos and albums isn't as simple as I thought it may be. So I started looking at some other options as far as alternative OS for the TouchPad. It looks like Android seems to be running quite well on the device (from what I've seen). So I was wondering if any of you could suggest a build / type of Android install I should attempt to use?
My needs are simple. I would like a nicer Photo Management software (if available with video playback for QuickTime / MPEG-4 files) and working Wi-Fi The ability to have multiple icons on a home screen is good. It makes it easier for her to select what she wants to do. Is there an option to make a keyboard larger? Or is there any font options to make things larger? She'll be 93 this month, and although her vision is pretty good, she can use all the help she can get.
Skype would be nice, but from what I understand camera and microphone compatibility is limited. Of course I'd like it to be as stable as possible. I haven't looked at her TouchPad in a bit, I'll see if there are any WebOS updates before continuing. But I'm curious as to what is out there to make this tablet a bit easier to use.
Thank you in advance for your help!

The CM9 builds are very stable and extremely usable. Try the nightly builds for good wifi. Also, the latest nightlies have working mic, though not camera.
There are tons of photo managers and video players on the Google Play Store; I like QuickPic for photos, but I don't watch a lot of videos.
The default homescreen has multiple icons.
There is an option for larger font in Settings -> Accessibility -> Large Text.
Several 3rd-party keyboards allow you to change the size of the keyboard. For example, I use SwiftKey, and it has 4 sizes. It is paid, though.
