Re: [CinCV] HDV to Vimeo / Youtube Workflow
Quoting Aaron Newcomb anewco...@gmail.com: This is pretty close to my workflow so I think you are on the right track. x264 is definitely better than mp4 if you are looking for good quality to file size ratio. wellx264 is a video codec where .mp4 is better a format for audio/video file. Maybe when you say mp4 you meant mpeg4, which is definitly a video codec you can compare with x264. While, for example: mpeg2 (standard format for dvd) or special mpeg you were trying to use to render from cinelerra are are slightly different, beeing lossless codec HIres; Where h264/.mp4 are better used as lossy low res(1280x720) option to upload video on hd mediabase (as vimeo is) :D vale I am playing around with my x264 ffmpeg command.

[CinCV] FOSS LINUX equivalent to ISOBuster??
I wondered if anyone on this mailing list might know of a free, open source LINUX utility equivalent to the commercial Windows program, ISOBuster? Sometimes, when I record a DVD on my stand-alone DVD recorder, I cannot access the data (something appears to go wrong in the finalization phase). K3B will recognize that there is data on the DVD, but is unable to mount the disk. I also tried mounting it using the mount command. It says that I must specify type. I tried with -t iso9660, which resulted in a message like wrong fs type Using dmesg | tail I get things like unable to identify CD-ROM format, and block 32 corrupted or cannot be read. In Windows, I can copy the DVD using Nero, but the resulting copy has the same problem. I cannot mount the DVD in Windows either. However, the free trial version of ISOBuster in Windows can recognize that all the usual video files are there. However, the trial version will not extract them. Before buying the commercial package for Windows, I have been trying to find out if anyone knew of a similar Open Source utility for LINUX to extract the recorded video from the DVD when something is wrong. By the way, I can usually still play such DVDs on the recorder on which it was made (but not any other). I would guess that about 20% of the DVDs I record have this problem. The others work fine. I cannot see any pattern as to why it works sometimes and not others. Thanks for any help. __ Yahoo! Canada Toolbar: Search from anywhere on the web, and bookmark your favourite sites.

[CinCV] add multiple uniform transitions at once to a track
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi August, you can add fades to the audio section as well if you arm only your audio tracks, jump from one edit to the next by using Alt+right or left arrow and insert the fade by pressing u. For setting the type and duration of the fade I recommend either experimenting around or the usual RTFM ;-) Hope this helps...

Re: [CinCV] add multiple uniform transitions at once to a track
Hi August! is it at all possible to add multiple uniform transitions to an audio or video track? I'm not sure it is your case, but when I have to insert a lot of dissolve transitions I edit directly the EDL (thank ichthyo for the tip!).
