![]() ![]() Geek Trivia - FourCC originated with the Mac, the Commodore Amiga and the Electronic Arts Interchange File Formatĭriver name – This displays the file name of the codec. In AVI files (MOV too) it’s used to identify the codec used. All of that to say Cineform uses P-frames!įourCC – This is short hand for Four Character Code and is a 4 byte sequence used to identify the data format. This extra savings comes at a high cost though as multiple frames must be decoded and held in memory before a B-frame can be fully decoded. B-frames are Bi-Predictive frames that save even more space by holding only the differences or deltas between the preceding and following frames. P-frames are Predicted frames and save space by holding only the differences or deltas from the previous frame so Delta frames is just another way of saying P-frames. I-frames are Intra-frames and are essentially fully specified, self-contained images. There are three basic types of frames used in video compression: I‑frames, P‑frames and B‑frames. Just to go over what the different things mean:ĭelta frames – This will be a little long to fully explain. Once selected you’ll see the Video codec information change. Go ahead and select the GoPro Cineform (native) entry as shown. ![]() Once you select one some information about it will appear on the right side. The left side lists the codecs you have available for use with VirtualDub FilterMod. This opens the compression properties window. To do that click Video then select Compression. The first thing we need to do is select the codec we want to use and set the output pixel format. There's a few settings we want to change before getting serious. We're going with the GUI version so double click VirtualDub.exe to start it and you should see this: VirtualDub.exe is the GUI version and vdub.exe is the command line version. Once it is unzipped you can move it to anywhere that's convenient for you. VirtualDub FilterMod doesn't have an installer and just needs to be unzipped. The latest release of VirtualDub FilterMod now has native Cineform support so you don't need anything from GoPro anymore.ĭownload the requirements of course GoPro Quik has a standard installer. Note – If you don’t need to fix VFR clips then this is all you really need transcode to Cineform. GoPro Quick Desktop w/Studio - This supplies a version of the Cineform codec that'll work with VirtualDub FilterMod. If you want to use the official VirtualDub instead you can and here is a PDF of the instructions for that.Ĭineform is what’s commonly known as an intermediate codec very comparable to ProRes and with the release of the Windows version of HitFilm Pro 2017 it’s natively supported making it the “go to” choice for an intermediate. Unlike VirtualDub, VirtualDub FilterMod supports deep color (16 bits per channel) and includes native import filters to handle clips from most cameras, phones, tablets and screen capture apps making it a lot easier to set up than the ‘official’ VirtualDub. It's a simple editor, it transcodes, it has batch processing with a queue similar to the new HitFilm render queue, a command line version for processing with a batch file and some unique plugins are available for it. Like VirtualDub it is a Ginsu Knife kind of utility for working with video files. VirtualDub FilterMod is a fork of the venerable VirtualDub. This tutorial covers using VirtualDub FilterMod to do just that fixing the audio sync issues and transcoding to the edit friendly Cineform codec at the same time. The only way to fix this problem is to convert the source to something with a constant frame rate (CFR). This is fine if all you want to do is playback a clip but all kinds problems can turn up when you try to edit it with the most common being the audio going out of sync. If your source clips were recorded with a cell phone, tablet or screen capture software odds are they were recorded with a variable frame rate (VFR). ![]() ![]() The last line below says to save to AVI, and those files don't have audio, but when we save as quicktime, the audio is there. Again the question is why we don't have any audio in the transcoded clips now. These for the instructions we are using for Virtualdub2. ![]()
