Original MTS file -= 15.34 bitrate
Produced M2ts file = 15.55 bitrate (this matches the bitrate in the profile)

So Fred, your bit rate actually increased when you ran your raw footage through SVRT.

A different result than mine...

Am I the only one that will have this result? It remains to be seen.

By the way....it's not a big deal.....but I thought that SVRT didn't change anything from the original....on my rig...it did.

The bitrate came from the profile..attempting to modify it (create custom profile) appears to disable SVRT.

The profile for the AVC h.264 1920X1080 is a default 15500 bit rate.....is that why it is dropping?

Maybe the answer is very simple.....I just didn't think it would drop below that number.

Probably I am just confused by all the numbers...Imagine that!!

Your custom profile sets a Min, Max and Ave Bit rate. From the bit of testing I have done if you original clips fit within these specs then the content will be copied to the output without any re-encoding (as SVRT should). However the header in the new file will be written with the profile specs by PD to describe the streams in the new file. So...in your case the video stream has not changed at all but the header info (that is read by Media Info) will have. You really don't know the "true" bit rate only what the Camcorder or PD decided to put in the header. The result is that while it is reported as changing the bit rate the stream is untouched if SVRT is used and an actual change in bit rate requires the clip to be re-encoded.

You bring up a good point about the header in the file being displayed. I typically don't use MediaInfo for bitrate because of that, I use the free utility bitrate viewer for comparison when checking files. It scans the file a gives a bitrate as a function of time or frame. It has some issues too with certain files, anyone else use a similar utility that they care to share the name of?

This is the same reason encoding the same clip numerous times will result in differing bitrates and duration (albeit very small differnces) Panasonic SD9, Panasonic TM700, Panasonic SD600, GoPro HD Hero.

As most of us use a Varible Bit rate any single figure should be taken with a grain of salt but they are are good approximation of what the files contains, and unless someone has modified the header or the app that wrote it is buggy so are progs like MediaInfo. If you want to see how the bit rate moves around both between and within clips then something like FFDSHOW will dynamically show you the input bitrate of the frames as they are processed (eg the attached is a snap shot only).

As I indicated, I use bitrate viewer which provides the plot below for a sample of Canon 24Mbps footage. I actually have a lens cap on for part of the footage because I wanted to see how much Canon may drop the bitrate depending on what is being filmed. As one considers proper bounds for SVRT I have in the past looked at ranges in my Canon footage and typically about 18Mbps for min and 24Mbps for max.

It has some issues for certain footages so was looking for an alternate tool.
