How to export from DV-NTSC to H.264 with one File, not separate A/V.

[hellyes0]

hey guys!

I need help. I just need to know how to make sure the video and audio both get encoded into one file. If I need to provie more details, let me know! Thanks!

A successful conversion could convert video and audio separately, but after that would combine both into one .mp4 file. The fact that you even asked the question seems to imply that you got a different result.

Please post the Process Information log, so we can look for clues why it didn't create one file with both video and audio. You may find this Process Information log by clicking the blue "i" in the ffmpegX Progress window after a conversion (attempt).

Yes, I did. I attached an RTF to this post. If you need it posted in plain text, let me know. Thank you in advance for your help. I really appreciate it.

x264 [warning]: MB rate (47652) > level limit (11880)

Apparently you used the "iPod h.264 320w" preset, but used a larger video size, a higher bitrate for both video and audio, and possibly changed some other settings as well.
First, the "iPod h.264 320w" preset sets the AVC level at 1.3 (see Options tab), which is aimed at the lower resolution of 320 px wide, as that level allows for only 11880 macroblocks per second, not 47652. For higher resolutions, you need a higher AVC level. But not too high, if you want to keep iPod/iTunes/iPhone compatibility.

x264 [error]: Error: 2pass curve failed to converge
x264 [error]: target: 3611.00 kbit/s, expected: 876.38 kbit/s, avg QP: 22.0000
x264 [error]: try reducing target bitrate or reducing qp_min (currently 22)

The (two-pass) encode can't do what it is asked to do: get about 3611 kbps with Qmin at 22. The default Qmin=10, Qmax=51 work quite well, with just 1429 kbps (for 848x480 @ 29.97 fps). 720x480: 1213 kbps. 640x352: 791 kbps. (Use the Best button in the calculator for a suggested optimum bitrate that goes with the video size, framerate and codec.)
Note that the encoder tries to keep the bitrate constant by varying the quantizer value between Qmin and Qmax, where lower quantizer values result in higher visual quality and higher quantizer values result in lower quality. By changing Qmin from 10 to 22, you are in effect lowering the quality of your output.

Input #1, wav, from 'foo.mov.wav':
Stream #1.0: Audio: pcm_s16le, 48000 Hz, stereo, 1536 kb/s
Output #0, mp4, to 'foo.mov.audio.mp4':
Stream #0.0: Audio: aac, 48000 Hz, stereo, 1536 kb/s
...
[aac @ 0x54340c]libfaac doesn't support this output format!
Error while opening codec for output stream #0.0 - maybe incorrect parameters such as bit_rate, rate, width or height

This seems to be the show-stopper. The uncompressed audio from the DV has the same bitrate as the highly compressed AAC audio output! 128 kbps will often be enough, anything over 320 kbps will likely not be supported!

With all this, I wonder what you aim is. Do you want/need playback on a certain device?

Hey! Thank you so much for all your help. I got that clip out and up on the site. I'm doing a web show called The Circuit and I needed it to be high res so the HD button would work int he flash player. You can take a look:

Thanks again!
