Very good budget option but you need to re-format it periodically.

One of the fastest cards available, but write speed is limited by a small buffer in the camera according to our card benchmarks.

In many cases, QScale settings around -8 will give results close to the default bitrate.Ĭards dSD cards (for 550D / 60D / 600D / 500D / 1100D) Card Note that unexpected changes in frame complexity may increase the bitrate to very high values, and the camera will stop recording. Use it to see the actual bitrate, which is displayed as: You will see a birate meter near the recording dot (550D/60D/500D). The exact bitrate varies a lot with frame complexity, and there is no direct relationship between QScale and the actual bitrate. You can set QScale value from -16 to +16, and lower numbers will result in higher bitrates. This mode is constant quality, variable bitrate (VBR). The following bitrate tests were done by DorianVasco with Bitrate Viewer, on a test scene on the desk without a lot of movement. CBR 1x is identical with firmware default setting. In Magic Lantern, you can set a scaling factor for the default bitrate. If the requested bitrate is higher than your card can handle, recording will stop as soon as frame complexity increases. In particular, when the scene does not contain too many details, QScale will reach -16 and the actual bitrate can be much lower than the one requested. CBR implementation still uses QScale as backend, and this parameter is limited to -16.+16. The exact bitrate achieved with CBR is still dependent on frame complexity. This mode uses (almost) constant bitrate, and therefore it's much more robust than QScale (less likely to stop recording due to sudden increase in frame complexity). Note: increasing bitrate will not reduce other artifacts like moire and aliasing, neither will influence the chroma subsampling.Īvailable Bitrates in Magic Lantern CBR You will need a fast card to handle the high bitrates cheap Class 10 Cards may not be fast enough for the high bitrate. The difference is mostly visible if you do heavy color grading.

If you want to get fewer compression artifacts, you may try CBR mode with a scaling factor higher than 1.

For example on a 16 GB Card you can achieve over 200 min recording with qscale -1 (this has been a real testing with slow action sequence).

If you want to record more than 12 minutes in 4 GB, or if you have a slow card (Class 4 or Class 2), use CBR mode with a scaling factor less than 1, or QScale with low negative values (e.g.

QSCale/CBR mode, or changing QScale by more than 1 step at a time).īit rate is adjusted in sub_FF1AAD00(width, fps, Sv) from CompressionRateAdjuster.c (550d/108).Ĭomparison: CBR1.8 vs CBR1.0, by PICMENTION Changing certain settings during recording will result in ERR70 (e.g. Some of these settings are only read when starting recording (like OptSize parameters) or continuously during recording (like QScale).

Head on over to the Magic Lantern to read more about the new features, or download the update using the link below. The money also allows them to continue developing updates and possibly get them working with newer cameras, like the Canon 5D Mark III and the Canon T4i. This stuff isn't easy, and all of the added features have taken years to really implement.

The team at Magic Lantern have worked incredibly hard, so if you do use your camera for professional jobs, and you install ML on your DSLR, it might not be a bad thing to head on over to their site and donate a few bucks. Video is no longer available: /lukeneumann/canon5dhdrvideo Luke Neumann put together this video showing off that capability: One of the most impressive parts of the new update has to be the HDR compatibility.
