| There is too many beginners who have a problem using those options. If phaeron resolve that, it would be even better for him, because he will spend less time answering to people's questions about this. So, here is my suggestions. 1. Currently, Smart rendering needs that user choose some video mode different of Direct stream copy, then he/she needs to set appropriately video codec. It would be nice if program could do this by itself. Obviously, user should have previously installed adequate codec. Anyway, I think if user choose the Smart rendering option, that Direct stream copy option in menu should be disabled. 2. We all know that VirtualDub can append only AVI segments which have same audio/video characteristics. If someone wants to append AVI files with different characteristics, he/she needs to recompress one or both parts using same audio/video settings. It would be nice if program could do this automatically, after asking user for affirmation. |

| added to ideas file Smart rendering auto-configure is problematic because of all of the settings on a modern codec... mixing B-frames with non-B-frame streams is not likely to work, even though VirtualDub couldn't tell that you had done this. The bitrate setting is also likely to be wrong. About the most that it could do is match the codec for you in the video compression dialog. |

| Thank you for considering this. Acctually, I think that automatic appending of AVI files is more needed, but now, when you are talking about Smart rendering... I think that problem is similar. If you decide to implement second suggestion - program needs to check audio/video codec of the first file, its bitrate, video resolution, audio sample rate... and to try to recompress second file with same characteristics. This is really hard task and I won't blame you if forget about this. I am just wondering - GSpot can detect if AVI file was compressed with B-VOPs, distance between them, packed bitstream... I know, it is obvious that your program could not cover all possible codecs, but I think that for most people it is sufficient to support XviD and MP3. It is better for users if you implement only this, than nothing. |
