<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial","sans-serif"">While technically you can put video and audio streams of other codecs into an MP4 container, doing so will give you files with reduced compatibility. H264 also has a bewildering
array of options which will also impact upon playback compatibility. One way to try avoid problems like this is to use an encoder or transcoding software and select a compatible 'profile'. Handbrake, for example, has built-in profiles for Apple devices where
such profiles set resolution and encoder features to be compatible and visually optimal on those devices. Those profiles tend to result in files that will play on pretty much anything, and you can always slightly modify them such as getting rid of a screen
size constraint for mobile devices.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial","sans-serif"">I would say that H264 + AAC is the defacto most supported (modern) file type now, and also has excellent performance. Of course the actual quality delivered very much depends
on the bitrate you have chosen. Using the 'quality' setting (often expressed as a percentage) is probably a more intuitive way to get to your desired size/quality trade off than using the actual kbps bitrate settings.<o:p></o:p></span></p>

<p class="MsoNormal" style="margin-bottom:12.0pt">Dear RNLD members,<br>
<br>
For those of you considering getting the Q4, I have discovered the following about it.<br>
<br>
I have been able to play the video files in real time, with both video and sound synchronically, by two methods:<br>
<br>
1) The original .mov file can be played using a player called NewPlayer<br>
2) I re-code the .mov file to .mp4 (using Xmedia Recode in my case) and play the .mp4 which then plays correctly in both KM Player and VLC Media Player.<br>
<br>
When recoding to .mp4, the new .mp4 files is around 1/10 the size. XMedia recode offers several different Video Codecs audio codecs and it also offers Audio/Video Synchronisation<br>
<br>
Can anyone advise which are best video codecs out of the following"<br>
MPEG-1<br>
MPEG-2<br>
MPEG-4<br>
MPEG-4 AVC/ H.264<br>
Motion JPEG<br>
XviD<br>
<br>
And the best audio codecs?<br>
AAC<br>
AC3<br>
MP2<br>
MP3<br>
Vorbis<br>
<br>

Stephen,<br>
<br>
I did some searching and found a website which has a few interesting comments on the Q4 (see below). In light of them and your own, you might try accessing the storage card/device through windows explorer (assuming you're on a PC) and copying the MOV files
from the camera directly to your hard drive and backing them up. Then use another piece of software (MPEG Streamclip, for example) to re-code the files from MOV to an MP4 container/extension for editing and playback. Hopefully that will work better - try it
with a short clip first, and if it doesn't work, experiment with a different format/extension.Hopefully the new files will be easier to play back and work with on your computer. Let me know if that helps.<br>
<br>
Best,<br>
Hiram<br>

1. Initial Status (Windows 7)<br>
• ZOOM HandyShare does NOT work with Q4 video. The video freezes. It messes up video/audio synchronization if trimmed. (It still can be used for WAV audio only files.)<br>
• QuickTime can play this video/audio format but video freezes or plays slow.<br>
• Windows Media Player -- good video but no audio. It can play PCM 24bit audio in nature but only play 24bit wav file of specific header information. (It worked fine for PCM 24bit after K-lite codec pack was installed.)<br>
