Video Conversion Script

[paug]

I have a custom video conversion script that has stopped working. My host is IMAGELEET. IMAGELEET says these switches work well:

/usr/local/bin/ffmpeg -y -chromaoffset 0 -i "INPUT VIDEO PATH" -acodec libfaac -ab 128k -pass 1 -s 640x352 -vcodec libx264 -b 786K -flags +loop -cmp +chroma -partitions +parti4x4+partp8x8+partb8x8 -me umh -subq 5 -trellis 1 -refs 1 -coder 0 -me_range 16 -g 300 -keyint_min 25 -sc_threshold 40 -i_qfactor 0.71 -bt 786K -maxrate 1.5M -bufsize 10M -rc_eq 'blurCplx^(1-qComp)' -qcomp 0.6 -qmin 10 -qmax 51 -qdiff 4 -level 30 -aspect 4:3 "OUTPUT VIDEO"

My programmer used this line of code:

ffmpeg -y -i 41.mov -threads 4 -s 640x480 -acodec libfaac -ab 128k -vcodec libx264 -crf 25 -rc_eq 'blurCplx(1-qComp)' -g 60 -coder 1 -cmp +chroma -partitions +parti8x8+parti4x4+partp8x8+partb8x8 -flags2 +brdo+dct8x8+wpred+bpyramid+mixed_refs -bf 16 -me_method umh -subq 6 -me_range 16 -i_qfactor 0.71 -b_strategy 1 41.tmp.mp4

I am trying to make High Quality Flash video for a site that has a bunch of flash videos. Which of these lines of code is better? The video player size is 600x400 for a 16:9 aspect ratio. If anyone can help me out please let me know. I would be more than happy to provide you with this custom script.

The first uses a video bitrate of around 786kbit/s(-b 786K) while the other uses Constant Quality-mode(-CRF 25). You usually get better quality using constant quality but bigger file size.

And if your source is 16:9 and you want a 16:9 output I would convert to a 16:9 resolution also like 640x360. (-s 640x360)

But I don't why it has stopped working without the ffmpeg error message output. Or your entire script that runs this.
