As you can see in the table above, Premiere Pro uses a fast, lower-quality algorithm for Playback by default.
This makes playback less demanding and may be the only workable choice on less capable systems. So you might find that your system struggles and starts dropping frames. Only when this feature is enabled will the program monitor truly reflect the final export. And this will affect how your compositing, cross-dissolves, and color grading will look. But even with GPU rendering, MRQ can improve quality when working with footage that supports fractional resolution Wavelet codecs, like RED for example , using full-resolution sources instead of a fractional resolution for the export when the image has been scaled down.
See Test And they mention that this list will change over time, as well as what impact MRQ has on them. But it only affects Software rendering. See Test 9. Here are two common statements. So, to get less banding and blocking when exporting using the standard export method, choose the same preset, you should activate MBD.
This is true for MRQ, but only if your timeline does not have a red render bar due to non-accelerated effects, which forces you into Software rendering. Not entirely true. Effects and transitions like Morph Cut and Optical Flow need to be rendered to see the actual result.
Effects and compositing can look very different before and after rendering. Glow effect made with a blurred copy below the original text before rendering.
Glow effect made with a blurred copy below the original text after rendering. If you want good quality video, always enable Maximum Bit Depth and Maximum Render Quality, and choose bit instead of 8-bit for formats with a choice for Depth. Most of the time, the settings will do nothing at all, but they will kick in when needed, and ensure the best possible quality. For longer projects I will set up watch folders in Adobe Media Encoder to automatically take my exported master file and output the h.
But for short-form projects I normally just queue these exports, which is fast and easy. I hope the info in this article enables you to make qualified choices for these settings for future projects. This should enable you to improve your image quality and yield fewer surprises when you export your films.
In the interests of transparency, here are the tests. They were run on a 7-year old laptop, so you may laugh at some of the export times. Here are the basic sequence settings and export settings. The basic sequence settings. The basic export preset. After each export, I performed a Difference Mode test, to see if any pixels had different values in the different versions. My main testing timeline was a minute long and contained a second clip repeated six times.
The source file was xpx, ProRes HQ, This matched the export, so in the first test, Smart Rendering kicked in, and the export time was very short.
Let me preface this by saying that these tests are not scientific. I had other software running in the background, and I timed the exports using the stopwatch app on my smartphone, so the timing may be off by at least one second, maybe more.
This is indicated by the very low CPU usage. Almost zero processing is going on, and the export is super fast. Conclusion: All the files are identical. I could see no difference in the program monitor or in the scopes—the waveforms were a straight flat line. They were also exactly the same size, down to the byte. Only when the export setting is changed does the file size differ, and a fuzzy line shows in the scopes. Files exported with MBD on in export settings are identical down to the byte no matter what the sequence setting is.
Files exported with MBD off in export settings are also identical down to the byte no matter what the sequence setting is. Conclusion: Export settings affect export times, and what algorithm is used. Sequence settings do not affect the exported files, unless you enable Use Previews in the export settings. When the export setting is changed the file sizes differ, and a fuzzy line also shows in the scopes. Conclusion: Export settings affect export times, and what algorithm is used, but sequence settings do not, unless you enable Use Previews in the export settings.
The export settings make an impact on the exported file—sequence settings have no influence on the exported file, unless you enable Use Previews in the export settings. Conclusion: When no scaling is going on, Premiere Pro uses Smart Rendering, and all the exported files are identical. Conclusion: Export settings affect export times in Software mode, and what algorithm is used, but Sequence settings have no impact on the exported files, unless you enable Use Previews in the export settings.
Export settings affect export times, and what algorithm is used, but Sequence settings have no impact on the exported files, unless you enable Use Previews in the export settings. All files exported with GPU enabled are identical, no matter what the sequence or export settings are. Only when the export settings are changed does the file size differ, and a fuzzy line shows in the scopes.
Sequence settings have no impact on the exported files, unless you enable Use Previews in the export settings. The two files are identical, down to the byte. Conclusion: Adding a non-accelerated effect to a clip forces Premiere into software only mode for the duration of the clip, even when the GPU acceleration is enabled in Project settings.
The test was performed with a 5. The four files exported with GPU enabled are identical, down to the byte, and difference mode shows a straight line in the waveform scope. When comparing exports done with MBD with GPU disabled , the line is straight, and the files are identical, down to the byte.
When comparing exports done without MBD with GPU disabled , the line is straight, and the files are identical, down to the byte. Conclusion: The MBD setting in the export settings affects render times and the exported file only in Software mode. The MBD switch in the sequence settings does not affect the final render unless you check Use Previews in the export settings.
The test was done with a 5. All four files exported with GPU enabled are identical, down to the byte. The files are not identical at all, and a Difference mode test shows a thick fuzzy line. CinePlay Professional video player.

Pro Maintenance Tools. Pro Media Tools. In that case, turn Maximum Render Quality on. Thank you for taking the time to write this. Just wondering your take on the two. Thanks again. Thanks for sharing your comments. I think the issue is the age of your system and the graphics card you are using, which is too old for Metal to work. Otherwise, turn this off. This setting is used to optimize the CPU for image scaling to avoid jagged edges on diagonal objects. Premiere uses Media Encoder for all exports — starting about a year ago.
The settings are identical for either application. I think jaggies occur during downscaling, which is what he may be referring to. I wish there was more unity in the answers.
Regarding prior question 2, When I check the Max Render in PPRo sequence, does that only affect the timeline render in PPro and has nothing to do with the export to disc? I hope my questions are understandable. While this may apply to down-scaling, image quality when making images smaller is much less an issue than when making them larger.
The only honest answer is try it and see. Unless you have strong lines — especially close to but not horizontal or vertical — you may not see a problem. In which case leave it off. Thanks, Steve. For the same project, the setting should match. Otherwise, the instructions above should hold true. HI Larry! Sigh… sometimes you just need more horsepower. Premiere is converting to GPU rendering, but it is a slow process. When rendering, Premiere will match the bit-depth of your sequence, unless you tell it otherwise.
Keep in mind that render speed will also be affected by the number and complexity of effects applied to the clips.
