HuffYuv and quality of the resulting file

[Disco Makberto]

Hi, there!

I have a simple question. When I use Super or Total Video Converter, and try to convert, for instance, a FLV file to an AVI file, the software gives the option of choosing from something like "high bitrate, normal bitrate, or lower bitrate". I don't understand this. If the HuffYuv codec is supposed to be a lossless codec, aren't we supposed to get the same bitrate on the resulting file? If we change bitrates, aren't we we re-encoding?

Greetings,

Dear eReaders,

There is no information about my question pretty much anywhere as I have looked via different search engines and different forums. However, I have inferred what they mean with "higher resolution, normal resolution, and lower resolution"....

1) Higher Resolution....Do they mean 100% percent resolution equal to the resolution of the non-converted file?
2) Normal Resolution....Do they mean less than 100% percent resolution when compared to the non-converted file?
3) Lower resolution....Do they mean still less than "less than 100" percent resoltuion when compared to the non-coverted file?

If I am correct, then 2) and 3) produce degradation in video quality. And, by the way, if I am correct, I don't agree at all with such wording as "higher resolution, normal resolution, lower resolution". Don't you find those terms confusing?

Please post your comments.

do a small sample in each and see what happens

Good advice, BJ_M! However, my trial version of Total Video Converter is expired or about to expire, but I will try. In Super, I think you have to choose the bitrate. So, if I go the Super route, I need to know the pre-existing bitrate on the non-converted file, but that is not hard to find out. At any rate, I will be reporting back soon, and thank you again for your assistance.

Cheers,

Can't say I've ever seen an option specifically that stated bitrate but there is and option for selecting compression level which in this case would would be the same thing.

According to here: http://neuron2.net/www.math.berkeley.edu/benrg/huffyuv.html#Configuring

Adjusting the compression level has no affect on the video according to what that documentation states but instead could be used for slower machines that drop frames during capture. Pretty much irrelevant on any recent computer or any computer if you're working with a file. It appears the best selection would be the highest compression so you produce the smallest file unless your machine is dropping frames.

Hello, CoalMan!

Thanks very much for your message.

I got it now. The resulting video has the same quality whether we use "high, normal. or lower". However, I didn't know that this so called "custom compression" was intended for slower machines. And you are right; this is pretty much a moot point with today's computers.

Good day, my e-(coal) man!
